His creation runs without gasoline, without a battery, and without traditional combustion, relying instead on a 200-year-old invention: the Stirling engine, patented in 1816. From there, he took on the challenge of building a full-sized Stirling engine capable of propelling a bicycle. With CNC tools, modern materials, and 3D printing, he managed to bring a centuries-old concept into the 21st century. Instead, Stanton’s project shows how old technology can inspire modern sustainable engineering. It’s proof that even the most outdated tech can find a second life — and maybe even shape the way we think about sustainable transport in the future.
